No need to change the MoBo.
You need to get into the BIOS and set "CPU operating
Speed" to the correct CPU speed according to the type and
the speed of your new CPU that is installed. During the
boot, before the Windows welcome screen, you should see
in the lower right corner of the screen what key/s to
press to get into the BIOS Setup menu.
It's possible the speed defaulted to a lower speed due to
no AC power being applied to the MoBo for awhile, which
might be a sign that the CMOS battery is losing its
charging ability for the CMOS memory to hold the correct
processor speed.
